   v1,
   v2         are two vectors of arbitrary dimension, the
              distance between which is desired.

   ndim       is the common dimension of v1 and v2.  ndim must be
              non-negative and must not exceed the minimum of the
              declared sizes of the actual arguments corresponding
              to v1 and v2.

   The function returns the distance between v1 and v2.  This is
   defined as

            ||  v1 - v2  ||,

   where || x || indicates the Euclidean norm of the vector x.

   If ndim is less than 1, the function value is set to 0..

   The Euclidean norm of an n-dimensional vector

      (x ,  x , ... , x )
        1    2         n

   is defined as

                                              1/2
            2        2                  2

           1        2                  n

   This number is the distance of the point (x, y, z) from the
   origin.  If n = 3, and A and B are two vectors whose components
   are

      ( a[0], a[1], a[2] )    and    ( b[0], b[1], b[2] ),

   then the distance between A and B is the norm of the difference
   A - B, which has components

      (  a[0] - b[0],  a[1] - b[1],  a[2] - b[2]  ).

   A related routine is <a href="vdist_c.html">vdist_c</a>, which computes the distance between
   two 3-vectors.
